[英]How to update multiple fields with NEST (Elasticsearch) UpdateByQuery?
[英]Elasticsearch NEST update by script
我正在嘗試通過腳本更新某些字段。 在郵遞員中,我發送以下請求:
https://search.test.com/items_example/item/en_01_2/_update
請求的正文:
{
"script": {
"inline": "ctx._source.Title = params.Title; ctx._source.Desc = params.Desc",
"params": {
"Title": "New Title",
"Desc": "New Desc"
}
}
}
但我不知道如何使用 NEST 發送此請求。 有人可以幫幫我嗎? Elasticsearch 5.4.1 版本,NEST 5.6.1
使用您的索引設置和查詢更新它
var elasticClient = new ElasticClient(settings);
var scriptParams = new Dictionary<string, object>
{
{"Title", "New Title"},
{"Desc", "New Desc"}
};
var response = elasticClient
.UpdateByQuery<dynamic>(q => q.Query(rq => rq.Term(....))
.Script(script =>
script.Inline(
$"ctx._source.Title = params.Title;" +
$"ctx._source.Desc = params.Desc ;"
)
.Params(scriptParams));
編輯:如果您只是在尋找更新,只需將語法更改為
var response = elasticClient.Update<dynamic>(
"items_example/item/en_01_2" //This is your document path
, request => request.Script(
script =>
script.Inline(
$"ctx._source.Title = params.Title;" +
$"ctx._source.Desc = params.Desc ;"
)
.Params(scriptParams)));
如果有人在這里尋找 NEST 6x 版本的解決方案,請參見下文
public async Task UpdateId(MetaData request)
{
try
{
var scriptParams = new Dictionary<string, object>
{
{ "Id",request.Id}
};
var script = $"ctx._source.Id= params.Id;";
var indexResponse =
await EsClient.UpdateByQueryAsync<Doc>(
qd => qd.Index(request.IndexName)
.Conflicts(Conflicts.Proceed)
.Query(
rq => rq.Term("_id", request._id))
.Script(
s => s.Source(script)
.Params(scriptParams)
)
)
);
if (!indexResponse.IsValid)
{
}
}
catch (Exception ex)
{
}
}
[ElasticsearchType(Name = "_doc")]
public class Doc
{
}
